Chapter 2 - Operation
Precautions
PRECAUTIONS
1) Only turn ON the input power supply after replacing the front cover. Do not remove the cover
while the inverter is powered up.
2) When the retry function (parameter L5-02) is selected, do not approach the inverter or the load,
since it may restart suddenly after being stopped.
3) Since the Stop key can be disabled by a function setting, install a separate emergency stop switch
to remove input power from the inverter.
4) Do not touch the heatsink or braking resistor, due to very high temperatures.
5) Since it is very easy to change operation speed from low to high speed, verify the safe working
range of the motor and machine before operation. Also, verify the parameter settings prior to oper-
ation.
6) Install a separate holding brake, if necessary.
7) Do not check signals during operation.
8) All inverter parameters have been preset at the factory. Do not change the settings unless it is
required.
Failure to observe these precautions may result in equipment damage, serious personal injury or
death.
